DETAILED DESCRIPTION

Vehicle windows can be large, and accordingly sometimes will not retract entirely within the door when lowered. Partitioning the window into a fixed section and movable section allows a portion of the window to be movable. However, partitioning can require a divider or other intermediate component that can detract from the appearance of the vehicle. A window area would generally be preferred to be seamless, without intermediate structures or seams, for a stylish appearance. The present disclosure is directed to window systems having a hidden division bar, thus providing a seamless appearance. For example, in some embodiments, the window systems of the present disclosure include division bars that are not directly visible outside of the vehicle when viewed at the elevation of the fixed window.

FIG. 1 shows a side view of illustrative vehicle 100 having hidden division bar 113, in accordance with some embodiments of the present disclosure. Vehicle 100 includes doors 110 and 120. Vehicle door 110 that includes a window region that includes fixed window 112 arranged in a first portion of the window region and movable window 111 arranged in a second portion of the window region. Fixed window 112 includes an exterior surface and an interior surface. Division bar 113 is arranged along a first region of the interior surface. Movable window 111 is configured to close against division bar 113, and division 113 bar is not directly visible from outside of vehicle door 110. Movable window 111, as illustrated, is configured to moved substantially vertically (e.g., vertical or off-vertical to follow the contouring of the vehicle which need not be exactly vertical and may include some slant or curve that deviates from vertical). The first portion of the window region is arranged at a top of the window region corresponding to fixed window 112. The second portion of the window region is arranged at a bottom of the window region corresponding to movable window 111. Division bar 113, as illustrated, is arranged substantially horizontally along the interior surface (e.g., including horizontal, slanting, curved, or compound shaped to follow the contouring of either fixed window 112 or movable window 211). Division bar 113, while horizontal or nearly horizontal (within 10 degrees) in some embodiments, may be oriented at an angle (e.g., slanted at any suitable angle), vertical (at 90 degrees from horizontal), or mostly horizontal with curves or steps to follow a contour. As illustrated, vehicle door 110 is a front door (e.g., a driver's side door) with the window region arranged between A-pillar 198 and B-pillar 199. Actuator 195 is configured to actuate movable window 111 substantially vertically (e.g., open and close movable window 111 along an exactly vertical, angled, or contoured path), and may include, for example, a motor, a linkage (e.g., a scissor mechanism), a rack and pinion mechanism, any other suitable components, or any combination thereof. To illustrate, movable window 111 is shown in a fully retracted position by the dash-dot line in FIG. 1, within the structure of vehicle door 110.

As illustrated, fixed window 112 is arranged laterally outside of movable window 111 such that fixed window 112 and movable window 111 are offset by a first distance. In some embodiments, as illustrated, fixed window 112 and movable window 111 overlap vertically by a second distance when the movable window is closed. As illustrated, because fixed window 112 and movable window 111 overlap vertically, division bar 113 is obscured from view from outside of vehicle 100. In an illustrative example, fixed window 112 includes a tint or fret arranged to visually obscure division bar 113 when viewed from the outside of vehicle door 110. For example, the entire fixed window 112 may be tinted or only a portion (e.g., a bottom portion). In some embodiment, the window assembly includes at least one seal arranged along division bar 113 such that movable window 111 is capable of closing against the seal. In some embodiments, the at least one seal extends along at least some of a perimeter of the window region to guide the movable window 111 as it opens and closes.

While not illustrated in FIG. 1, in some embodiments, a movable window may be configured to moved substantially horizontally, with the first portion of the window region arranged at a front of the window region and the second portion of the window region arranged at a rear of the window region. In some such embodiments, the division bar is arranged substantially vertically along the interior surface.

FIG. 2 shows a side view of illustrative vehicle door 200 having a hidden division bar (e.g., division bar 213), in accordance with some embodiments of the present disclosure. FIG. 3 shows a side view of a portion of illustrative vehicle door 200 of FIG. 2 from the outside, in accordance with some embodiments of the present disclosure. FIG. 4 shows a side view of a portion of illustrative vehicle door 200 of FIG. 2 from the inside, in accordance with some embodiments of the present disclosure. FIG. 5 shows an elevated perspective view of a portion of illustrative vehicle door 200 of FIG. 2 from the outside, in accordance with some embodiments of the present disclosure. FIG. 6 shows a side view of a portion of illustrative vehicle door 200 of FIG. 2 from the inside, illustrating division bar 213, in accordance with some embodiments of the present disclosure.

As illustrated, vehicle door 200 is similar to vehicle door 110 of FIG. 1, having fixed window 212, movable window 211 and division bar 213. Vehicle door 200, as illustrated, includes outer panel 220 and inner panel 221, which are joined to form the structure of vehicle door 200. Fixed window 212 is either not movable, or otherwise not retractable into vehicle door 200 as movable window 211 is. For example, fixed window 212 may be stationary, or may be capable of tilting or partially opening outward (e.g., to vent). In some circumstances, a window area is partitioned into fixed and movable regions because a single window the size and shape of the entire window region would not fit within the door. As illustrated in FIGS. 2-6, movable window 211 is capable of being fully lowered below the window region in vehicle door 200.

In some embodiments, as illustrated, division bar 213 is formed at least partially by inner panel 221, which includes formed sheet metal (e.g., as illustrated in FIG. 4). In some embodiments, vehicle door 200 includes a mechanism (e.g., indicated by mechanism 299 within the structure of vehicle door 200) to raise and lower movable window 211 such as, for example, an electric motor coupled to linkages, a rack and pinion assembly, any other suitable automatically or manually operated assembly, or any combination thereof. As illustrated in FIG. 5, a lateral offset may exist between fixed window 212 and movable window 211. For example, fixed window 212 is located laterally a distance outside of movable window 211. To illustrate, the distance may be fractions of an inch (e.g., a quarter, a half, three-quarters of an inch, or any other fraction), or more, in accordance with the present disclosure. Seals 222 (exterior) and 223 (interior) may extend along the perimeter of movable window 211, fixed window 212 or both (as illustrated).

Window assembly 1200 includes first window 1212, second window 1211, and division bar 1213 (e.g., arranged along region 1214 of first window 1212). The outside and inside of window assembly 1200 are annotated in FIG. 12. First window 1212 and second window 1211 are laterally offset by a distance “L,” which may be an inch, a fraction of an inch, or larger than an inch. First window 1212 and second window 1211 overlap by a distance “H,” which may be an inch, a fraction of an inch, or larger than an inch. In some embodiments, the distance “L” is minimized or otherwise designed to be relatively small (e.g., fractions of an inch, or 17 mm or less) to provide a seamless appearance. Division bar 1213 may include, for example, sheet metal, rubber, seals, any other suitable components, or any combination thereof.

In some embodiments, FIG. 12 shows a cross-section view as viewed in a substantially horizontal direction (e.g., forward or rearward, wherein Direction 1 is vertical and direction 2 is lateral). Substantially horizontal includes exactly horizontal, angled from horizontal, contoured to follow a path that is mostly horizontal, or otherwise following a path that from end-to-end is elevated less than 45 degrees from horizontal. Accordingly, in some such embodiments, first window 1212 is an upper window and second window 1211 is a lower window. In some embodiments, second window 1211 is movable (e.g., along direction 1).

In some embodiments, FIG. 12 shows a cross-section view as viewed in a substantially vertical direction (e.g., upwards or downwards, wherein Direction 1 is horizontal and direction 2 is lateral). Substantially vertical includes exactly vertical, angled from vertical, contoured to follow a path that is mostly vertical, or otherwise following a path that from end-to-end is elevated more than 45 degrees from horizontal. Accordingly, in some such embodiments, first window 1212 is a front window and second window 1211 is a rear window. In some embodiments, second window 1211 is movable (e.g., into or out of the page as illustrated in a direction normal to both Direction 1 and Direction 2). In some such embodiments, fixed window 1212 is arranged laterally outside of movable window 1211 by a first amount such that fixed window 1212 and movable window 1211 substantially form a backwards-facing step (e.g., Direction 1 is forward, towards the front of the vehicle).
